Last week we took a look at nine free iOS apps to help you track expenses and mileage, organize bills, calculate on the go, budget, make smart purchases, and track packages. This week we focus on free productivity apps for project management, paperless meetings, better communication, security, task management, file sharing and storage, workflow, video conferencing, scanning, PDFs, eSigning, notetaking, sketching, languages, and business travel.

Project Management

Trellois the free, flexible, and visual way to organize anything with anyone. Forget lengthy email threads, out-of-date spreadsheets, sticky notes, and clunky software for managing your projects. Trello lets you see everything about your project in a single glance. Compatible with Apple Watch.

Better Communication

Rather than worrying about your data allowance or cell signal, WhatsApp lets you send messages over Wi-Fi or a mobile data connection instead. Send and receive photos free over Wi-Fi* with no size restrictions. (*Or if you have unlimited mobile data.)

Share projects, assign tasks, and add comments all within the app. Instant notifications will keep you up-to-date whenever changes are made. Compatible with Apple Watch.

EasilyDo connects to online services, like your email, calendar, and Facebook, then looks for things it can help you get done. For example, it might ask you if you’d like to add contact details of someone who emailed you to your address book. Or it might spot an upcoming birthday. (Best for personal use.)

File Sharing and Storage

Transfer files instantly across Mac, iOS, Android, and Windows platforms using simple drag and drop with Instashare Air Drop. Transfer any file type (MP3, images, PDF, slide decks, docs, and more).

Workflow

The custom keyboard doesn’t log any of your input and requires no use of the Internet. Sync across all iOS devices through your private iCloud account with the Pro version. Compatible with Apple Watch.

“If this, then that.” Use ifttt to automate just about anything: create events in Google Calendar with only a few taps; keep your team in sync with scheduled reminders for Slack; catalog important email from your inbox in an Evernote notebook to go over later; sync files quickly.
